LAN D-ROLLER.

QPECIPICATION' forming part of Letters Patent No. 383,807, dated May 29,1888.

(No model.)

To all whom, it may concern:

Be it known that I, FRANKLIN Gnnuns, a citizen of the United States ofAmerica, residing at Richland Station, in the county of Lebanon andState of Pennsylvania, have invented certain new and useful Improvementsin Land-Rollers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention pertains to certain new and useful improvementsinland-rollers,having for its object the production of a land-rollerhaving simple and highly-efficient means for rolling uneven ground orsoil by constructing the parts of the land-roller in hinged or pivotedsections, each connected to but independent of the other, so that eachsection or roller can readily conform to any inclination in the earthover which it passes.

The invention therefore comprises the detail construction, combination,and arrangement of parts, substantially as hereinafter fully set 'forth,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of myinvention.Fig. 2 is a rear view thereof, and Fig. 3 is a sectional View.

Referring to the drawings, A indicates the main frame of my improvedland-roller, the

same consisting preferably of a central bar, a, and two divergent bars,aa, connected at their forward ends to the forward end of said bar a,the meeting ends of these bars being preferably covered by a cap-piece,a", as shown.

B is a front supplemental frame, composed of two longitudinal bars, I)b, connected at their ends and center by short cross-bars b. The centralcrossbar, b, is connected to the rear end ofa tongue or pole, D which ispivotally se cured to the forward end of the frame A by means of twoconnecting links or staples, b, so as to permit the supplemental frame Bto have a pivotal movement with relation to said frame A.

O O are two rollers pivotally secured between downwardlyprojectinghanger-plates d d, the upper ends of which are secured to thesupplemental frame B, said rollers being free to revolve between saidhanger-plates under the supplemental frame without coming in contacttherewith.

A series of three or more rollers, D D, are disposed in rear of thesupplemental frame B, and are designed to normally occupy a transverseplane parallel therewith. Each of these rollers D D is pivotally securedbetween two hanger'plates, d (1', attached at their upper ends to theside bars of preferably squareshaped frames d (2 The frame of thecentral rail-roller,- D, has rigidly secured thereto the rear end of thecentral bar, a, of the frame A, and to the side bars of this frame aresecured apertured ears or plates 6 (2, through the apertures of whichare passed U-shaped bars 0' e, the outer ends of which are looselysecured to the front and rear bars of the frames b b by means of screwspassed through looselyfitting apertures thereof. In lieu of making thesebars U-shaped, the side arms thereof can be connected directly to eachapertured ear or plate e, and the connecting-bar (shown as being passedthrough the apertures of said ears or plates) can be dispensed with, asis obvious.

Through central staples secured to the upper surfaces of the front andrear bars of the frames 1) b are passed brace-rods ff, which areslightly curved at their forward ends, and are loosely secured by meansof nutted bolts f to apertured plates f attached to the outer rear endsof the divergent bars a a.

The frame of the central roller, D, is held in position by shortinclined brace-rodsff secured thereto and to the divergent bars of theframe A. Over the frame of the rear central roller, D, is secured theoperators or drivers seat G, the brace-bars g of which are attached tosaid frame and to the central bar, a, of the frame A.

It will be observed that the rollers G G of the supplemental frame Boccupy the space between each two rollers of the rear series a shortdistance in front thereof, and that the central roller, D, occupies thespace between the two front rollers, O C, but in rear thereof, wherebythe rollers of one series pass over that portion of the earth notaffected by the rollers of the other series.

From the foregoing description it will be seen that the outer rollers ofthe rear series have a pivotal movement,which permits them to conform toany inclination in the earths ICO surface, so that either one or both ofsaid end rollers can be upon a hill or inclination without affecting theother central roller.

By reason of the hinged connection between the central roller, D, andthe end rollers it will be seen that by removing the nutted boltsconnecting the curved brace-rods f to the frame A either one of said endrollers can be turned over onto the central roller, D, so as to diminishthe space occupied by the rear series of rollers in passing through anarrow space, which feature is a'desideratum in this class ofinventions. Said rollers, when so placed upon the central roller, restupon the seat thereon.

I claim as my invention In a land-roller, the combination of the roller-frame, the supplemental frame connected thereto and carrying rollers,the rear series of rollers, the U-shaped arms pivotally connecting theend rollers of said series with.
